8.1 Setting the cutting gap tolerance
The cutting gap is adjusted after initial commissioning
and after each knife change.
- If the cutting gap is set too large, the notching
process may result in burr and chip formation. If the
cutting gap is set too small, the knives may be da-
maged and the stroke may block.
- Perform a few test cuts after adjusting the cutting
gap.
Step 1: Disconnect the power supply.
Step 2: Unscrew the screws (Pos. 2, Fig. 13) then re-
move the safety cover (Pos. 1, Fig. 13).
Step 3: Loose the bias screws (Pos. 4, Fig. 13) and
blade screws (Pos. 5, Fig. 13).
Step 4: Measure the tolerance by 0.25 mm thickness
gauge (Pos. 6, Fig. 13).
Step 5: Adjust the upper and lower blades against to the
thickness gauge. The thickness gauge should
be nower removed smoothly.
Step 6: Tight all the screws.

ATTENTION!
Settings on mechanically acting machine elements
may only be carried out on the machine by trained
specialists or specially trained and instructed per-
sons.
DANGER!
Incorrect mechanical settings can influence the
safety of the machine to such an extent that it cau-
ses a permanent danger. Careless behaviour can
put the personnel and the machine at risk when swit-
ching-on again.
- Before making any mechanical adjustments, al-
ways switch off the machine at the main switch and
secure the main switch against accidental restar-
ting, e.g. by attaching a warning sign.
- After carrying out the adjustment activities, make
sure that all covers and protective devices have
been properly mounted on the machine again.
- Do not leave any tools accidentally inserted during
setting activities. Before switching on the machine
again, make sure that all setting tools have actually
been removed. Make sure that no tools are left in-
side the machine, especially in the working area of
the machine mechanics.
ATTENTION!
There is a risk that the machine will be damaged if
the cutting gap is set incorrectly.
Use protective gloves!
ATTENTION!
No adjustment of the cutting gap is required for dif-
ferent sheet thicknesses. There are spring plates in
the system which automatically adjust the cutting
gap.

8.2 Changing the knife
Replace the knives in time. Blunt knives lead to poorer
cutting performance.
- Poor knife quality reduces the service life of the
knives.
- There is a danger that after a knife change the cut-
ting gap is incorrectly set and the machine is dam-
aged.
- Use protective gloves when changing the knives.
- After each knife change, make sure that the cutting
gap is within the permissible setting range of 0.25
mm.
- If necessary, readjust the cutting gap.
Replacing the upper knives:
Step 1: Move the knife bar to the upper end position and
switch off the machine by actuating the main
switch. Now secure the main switch against be-
ing accidentally switched on again.
